cole I hate to disagree with you but a m48 in .22cal most of them ave 800fps+ with 14.3gr pellets and a 34 with the best tune will only be around 730ish with the same pellet weight,
I prefer to buy used. The gun should already be broken in, you know it isn't a lemon, and I am looking for an already tuned gun. You can get a much better deal in the used market, and the gun is usually better than buying new, especially if you don't know how to tune a gun.
